Task Assignment in Distributed Systems
This thesis addresses the problem of task assignment in distributed systems. A distributed system is defined as any configuration of two or more processors, each with private memory, in which computations utilize the combined resources of the component machines. A distributed process is defined as …

Consensus-based auctions for decentralized task assignment
This thesis addresses the decentralized task assignment problem in cooperative autonomous search and track missions by presenting the Consensus-Based class of assignment algorithms. These algorithm make use of information consensus routines to converge on the assignment rather than the situational …

Robust and decentralized task assignment algorithms for UAVs
… thesis investigates the problem of decentralized task assignment for a fleet of UAVs. The main objectives of this work are to improve the robustness to noise and uncertainties in the environment and improve the scalability of standard centralized planning systems, which are typically not practical …

Distributed Dynamic Hierarchical Task Assignment for Human-Robot Teams
This work implements a joint task architecture for human-robot collaborative task execution using a hierarchical task planner. This architecture allowed humans and robots to work together as teammates in the same environment while following several task constraints. These constraints are 1) …

Task assignment algorithms for teams of UAVs in dynamic environments
… an approach to decompose this large problem into task assignment and trajectory problems, while capturing key features of the coupling between them. This enabled the control architecture to solve an assignment problem first to determine a sequence of waypoints for each vehicle to visit, and then …

Reducing Interprocessor Communication in Parallel Architectures: System Configuration and Task Assignment
Most future supercomputers will be based on parallel processing architectures. Currently, many applications with sufficient parallelism cannot efficiently run on large parallel processing systems because interprocessor communication and synchronization significantly degrade performance. …

QoS and security-aware task assignment and scheduling in real-time systems
… Based on the imprecise computation paradigm, a task can have several Quality of Service (QoS) levels, higher QoS result incurs higher computational cost. Similarly, achieving a higher level of confidentially requires stronger encryption, which incurs higher computational cost. Therefore, there …

Optimal Order Assignment with Minimum Wage Consideration (OOAMWC)
… of the issues that affect crowdsourcing include task assignment, profit maximizations, as well as time window issues. In some instances addressing some of the issues results in the other issues being overlooked. An example is when assigning tasks to workers, the profits of the workers might not …
